ns1 should not be a CNAME. Make it an A record like jefferson;
and maybe make jefferson and the others CNAMEs to ns1.

Resolve what? You don't have an A record for progressivetrail.org,
so dig won't find one if you ask for it. (Also, progressivetrail.org
is not a top-level domain, it is a second-level domain; org is the TLD)

It is used by secondary/slave servers to detect if the zone on the
primary/master server has been updated; the zone admin is expected
to increment the serial number with each change. The recommended
format of the serial number is yyyymmddnn, eg 2004120601 means the
first change on 6-Dec-2004.

That should be updated.

Expire should probably be a lot longer.

Bad idea, as above.
